#178977 - Sign of a cheap & nasty adaptor Responding to: ???'s previous message |

... it is common that when you put the same USB->Serial cable from one USB port and into another USB port that the virtual Comm Port number changes. Yes - this is a common feature of cheap & nasty USB-Serial adaptors. I'm not sure if the Prolific chips are inherently cheap & nasty, or it's just that they tend to get used in cheap & nasty adaptors...? FTDI adaptors don't do this - they keep the same COM number irrespective of which USB port you use... http://www.8052.com/forum/read/176508 |
